When Kiran moved into a new house, he planted two trees in his backyard. At the time of planting, Tree A was 33 inches tall and Tree B was 15 inches tall. Each year thereafter, Tree A grew by 4 inches per year and Tree B grew by 7 inches per year. Let AA represent the height of Tree A tt years after being planted and let BB represent the height of Tree B tt years after being planted. Write an equation for each situation, in terms of t,t, and determine the interval of time, t,t, when Tree A is taller than Tree B.
